The sum of all external angles in any polygon is always  360 degrees.All you have to do is add up all the values of the angles and equate  it to 360
Like this-
(x+16)+(3x-1)+6x+5x=360
Can you do it now @I_need_help_please ?

For more info on "exterior angles," please see the following: https://www.mathsisfun.com/geometry/exterior-angles-polygons.html I didn't know this theorem about the sum of exterior angles myself, so had to look it up. always a good idea to look up things that are unfamiliar or hazy for you.
